The mechanism is the Trans-Pacific Partnership. Negotiations have been conducted in extreme secrecy, so you are in good company if you have never heard of it.

The TPP has been cleverly misbranded as a trade agreement (yawn) by its corporate boosters. As a result, since George W. Bush initiated negotiations in 2008, it has cruised along under the radar. The Obama administration initially paused the talks, ostensibly to develop a new approach compatible with candidate Obama’s pledges to replace the old NAFTA-based trade model. But by late 2009, talks restarted just where Bush had left off.

Since then, US negotiators have proposed new rights for Big Pharma and pushed into the text aspects of the Stop Online Piracy Act, which would limit Internet freedom, despite the derailing of SOPA in Congress earlier this year thanks to public activism. In June a text of the TPP investment chapter was leaked, revealing that US negotiators are even pushing to expand NAFTA’s notorious corporate tribunals, which have been used to attack domestic public interest laws.
